This bill, titled the Frequent Logistics Information for Grounded and Held Travelers Act (FLIGHT Act), aims to enhance passenger communication during flight delays. It amends title 49, United States Code, to establish new requirements for air carriers. Specifically, for any domestic or international flight experiencing a delayed departure or taxi delay of 15 minutes or more , the operating airline must notify each passenger. These notifications must be sent via email or text message at least every 15 minutes until the delay is resolved. Each notification is required to include the new estimated time of departure and arrival . Additionally, passengers must be provided with a mechanism to opt out of receiving further notifications for that specific flight.
